Well I was referring to the idea that cholesterol and fat are no longer thought to be the cause of heart disease but they do still see correlation with red meat consumption. And also research that if you eat a meal with red meat, your risk of heart attack increases immediately after the meal.
Here is one article from last year but I think there were multiple similar studies

Also, one thing I thought about is I read that there has also been a lot of research regarding diabetes and exercise. One research study I read last year talked about using walking after meals as a means to control diabetes. The study participants were able to control their blood sugar by simply walking. I know a lot of cultures walk after meals or just walk a lot in general (which we Americans don't outside of major cities with good transportation systems).
Now the study just applied to diabetics but if we think spikes in blood sugar can damage our cardiovascular system, then walking or gentle exercise after meals may be a way to help prevent that.
